PDF Redewendungen | THE HEART AND THE VASCULAR SYSTEM

Veins are the large return vessels of the body and act as the blood return counterparts of arteries. The high surface area to volume ratio of erythrocytes allows oxygen to be easily transferred into the cell in the lungs and out of the cell in the capillaries of the systemic tissues.The heart pumps oxygenated blood out of the left ventricle and into the aorta to begin systemic Systemic circulation facilitates internal respiration: Oxygenated blood flows into capillaries through The systemic veins feed into the inferior and superior venae cavae, the largest veins in the body.Venules drain into small veins that open into larger veins. • Largest veins, superior and inferior venae cavae, return low-oxygen blood to the heart. Great ability to stretch (capacitance) Function as reservoirs: blood pools in the valves then is pushed forward from the pumping pressure.Translate into English: 1. Во рту находятся десны с зубами, язык и нёбо. The circulatory system consists of the heart and blood vessels and the blood which is pumped through the blood vessels by the heart. The large cavity is called the cranial cavity.The heart is enclosed in a pericardial sac that is lined with the parietal layers of a serous membrane. The internal cavity of the heart is divided into four chambers The right atrium receives deoxygenated blood from systemic veins; the left atrium receives oxygenated blood from the...

Pulmonary & Systemic Circulation | Circulatory Anatomy

This is sometimes called the greater or systemic circulation. Many features of the systemic circulation are duplicated in the pulmonary circulation. The pulmonary artery subdivides into branches, which finally end in the pulmonary arterioles and capillaries. The lower pressure against which the right ventricle works means that its power requirement is much less than that of the left.The heart is a muscular pump that pushes blood through blood vessels around the body. Blood vessels form the living system of tubes that carry blood both to and from the heart. A special part of the brain, called the medulla oblongata, receives information from many different systems of the body.The pressure in the large systemic veins leading into the heart is called what? The elastic nature of the largest blood vessel's walls allows them to act as a _, maintaining the driving force for blood flow while the heart is relaxed during diastole.This decrease in pressure is called a pressure drop. However, the pressure gradient in the pulmonary circuit is considerably less than that through the systemic circuit. Veins can accommodate a large increase in blood volume because of their high compliance (expansion due to...

PDF Cardiovascular System Resimsiz

Changes of pressure allow the blood to flow through the cardiac cycle. This is controlled by the cardiac conducting system and regulated by the medulla via the autonomic nervous system. the vena cava is the largest vein in the body. It carries deoxygenated blood from the body back to the heart.The heart contains two upper chambers called atria and two lower chambers called ventricles. The heart is located in the thoracic cavity between the lungs and protected by the rib cage. The pulmonary vein and aorta also have valves connecting them to their respective ventricle.The systemic circulation is the portion of the cardiovascular system that carries oxygenated blood from the The vessels that deliver oxygen-rich blood to the heart muscle are called coronary arteries; they branch directly from What is the difference between pulmonary circulation and systemic circulation?Введение What is the first aid? Bruise Bleeding Fracture Fainting Shock Sunstroke Poisoning Burns • The lack of blood flows to the blood vessels supplying the heart muscle. • The result of eating Ex1. Translate from English into Russian: The cause of fainting; hunger; the face gets pale; sweat appears...The cardiovascular system is part of the larger circulatory system, which circulates fluids Veins: Blood vessels that return blood to the heart. Capillaries: Very small vessels that lie between the After systemic circulation, the blood in the right atrium is depleted of oxygen, so it needs to go to the lungs...
